Micronutrients are defined as nutrients that are required in smaller amounts compared to macronutrients, which include carbohydrates, proteins, and fats. They primarily consist of vitamins and minerals, which play crucial roles in various bodily functions, including immune support, energy production, and overall metabolic processes. Micronutrients do not provide energy directly but are essential for the body's ability to utilize macronutrients effectively.

The significance of micronutrients lies in their role in preventing deficiencies and supporting health, even though they are needed in much smaller quantities. Unlike macronutrients, which are consumed in grams, micronutrients are typically required in milligrams or micrograms, yet they are vital for proper growth, development, and disease prevention. Understanding this distinction is crucial for appreciating the importance of a well-balanced diet that includes an adequate amount of both macronutrients and micronutrients.
